Fine Chemicals

 

Business Activities

The Fine Chemicals business unit is centered on organic compound technologies. Its main business fields are eyeglass-related materials and pharmaceutical technical products and intermediates.

Our major eyeglass-related products are photochromic materials. These materials are characterized by becoming colored when exposed to strong sunlight and becoming transparent when shielded from exposure. By taking advantage of their properties, that is to change colors between transparent and colored and to block ultraviolet rays, they are mainly used in sunglasses. For photochromic lenses, there are two types of manufacturing processes. One of them is mixing photochromic compounds, which become colored by sunlight, with plastic lens (monomer), and another is coating photochromic compounds on the surface of plastic lenses, both of which can be taken by our company.

As the depletion of the ozone layer proceeds, global demand for photochromic products is increasing. Tokuyama is aggressively developing operations mainly in Europe, where sunglasses are accepted to people’s particular liking, while also taking the U.S., the world's largest market, into consideration. Tokuyama also produces and markets hard coatings that are applied to lens surfaces to prevent scratching, coating materials for preventing water stains on lenses, basic materials for plastic lenses, and primer that increases adhesion strength of coatings on lenses.

The "bulks" of pharmaceutical are technical grade of compounds synthesized specifically for the production of pharmaceuticals. Intermediates are organic chemical compounds used as intermediate materials in pharmaceuticals, paints, and dyes. In the Fine Chemicals business unit, we also concentrate our efforts on pharmaceutical technical products and intermediates operations, including contract manufacturing and bulks of generic medicines which is promoted by the goverment recently.

In the production of pharmaceutical technical products, Tokuyama follows Good Manufacturing Practice (GMP) guidelines to manufacture products of the finest quality in accordance with the Pharmaceutical Affairs Law of Japan. GMP comprises structural facility standards for factories, as well as production management and quality control standards. In Kashima Factory, we produce high quality products based on facilities and management practices in line with GMP standards.
